# MicMap bindings-patcher shared library (Phase 4 D-10 lift)
#
# This library hosts the C++ logic that patches SteamVR's system-level
# generic-HMD vrcompositor bindings so an HMD's /input/system/click routes
# to the SteamVR dashboard + head-locked lasermouse leftclick. Lifted out
# of driver/src/bindings_patcher.{hpp,cpp} so that both driver_micmap.dll
# and micmap.exe can link a single source of truth.
#
# DriverLog dependency is replaced by an injected LogSink
# (std::function<void(const char*)>) so the library carries no driver-only
# symbols and remains testable without a live SteamVR runtime.
